I do think that they should be paid for this work, and be able to sustain themselves from it. So I wouldn't be against it being a business, or the project having a subscription model. The idea of open source being gratis, and products in general being "free", has done enough harm to the world.
100% so many projects have died because they didn't have a longterm plan to keep the lights on other than hoping for donations and or offering support that no one needed (the better the project the less likely you need support).
